MSN Movies has an interesting article talking about how the shooting dates for X-Men 3 and Superman conflict. Here’s a clip:

According to my sources, 20th Century Fox nixed the idea of up-and-coming Ashmore starring in Warner Bros’ new Superman feature. Fox is telling actors who have options for the third, untitled X-Men film that it will begin shooting June 20th. That conflicts with “Superman Returns'” spring shooting schedule, which is anticipated to go through July 30.
